Excellent Solid State or Hybrid Monoblocks Recommendations

@ yyzsantabarbara I sold my Coda #16 amp last year.  My modded LSA Voyager GAN amp is worth a lot more to me than I could ever get for it by selling it.  Class D has come a long damn ways.  I suspect that the gan fet is a chunk of this progress assuming it is well implemented.  I am gonna pick up some class D monoblocks in the near future.....

I too have a pair of BHK 300 monos powering my Kef Ref 5's.  Front end is a DCS Bartok. I haven't got round to tube rolling yet but one day .... 

What I can say is I push my system very loud at times and it just keeps on giving. The amps barley get warm. They seem to have so much left in reserve. You can switch them into 'standby' which turns off the tube input stage but maintains power to the electrictronic circuits. All I can say is I am very happy with them

Would suggest checking out Concert Fidelity monoblocs

I thought you had a moded Voyager. Many times the itch for something else doesn't pay dividends you hoped for

Do you have all you cable connections treated with something like Mad Scientist Graphene Oxide Enhancer. It is jaw dropping. I did one component at a time starting with my transport. It was incredibly obvious, but I persevered staying with one component at a time. Each time the sound got better and better

The absolute best amps I heard running Aerials were Jeff Rowland amplifiers (of course this was decades ago, so YMMV).

On the other end of the economy scale, I’d suggest checking Odyssey Audio monoblocks; they offer terrific bang per buck.

Good luck & happy listening!
